CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. §119 to Canadian Patent Application No. 2,574,722 entitled “SYSTEM FOR REINFORCING A BUILDING STRUCTURAL COMPONENT” filed Jan. 22, 2007, the contents of which are hereby incorporated by reference.

FIELD OF INVENTION

The present invention relates to a system for reinforcing a building structural component.

BACKGROUND OF INVENTION

Various systems for reinforcing building structural components have been proposed. Typically, the systems include one or more stirrups and a series of reinforcing bars, which are combined to form a cage-like apparatus. For example, U.S. Pat. No. 6,293,071 (Konstantinidis) discloses a system for reinforcing load bearing building elements. U.S. Pat. No. 6,293,071 describes a system that includes a stirrup with a plurality of windings in combination with reinforcement bars. U.S. Patent Application No. 2005/0257482 (Gallucchio) discloses a system that employs a single continuous stirrup along with a plurality of reinforcement bars. The stirrup may be compressed for ease of transport. Finally, U.S. Patent Application. No. 2006/0207211 (Yin) discloses a system with a number of spiral stirrups, each having a series of reinforcing bars.

Systems for reinforcing building structural components may be used with insulated concrete formwork or block masonry. Insulated concrete formwork typically includes webs that join the insulation panels orientated on both sides of the concrete formwork, while block masonry includes webs that join the face shells of the blocks. As such, normally, rigid individual stirrups and reinforcing longitudinal bars must be placed during the construction of the insulated concrete formwork or concrete masonry. A limitation of the prior art structural systems is that the complex combination of stirrup reinforcement and longitudinal reinforcing bars formed into reinforcing cages cannot be used for subsequent construction of insulated concrete formwork or block masonry. A further limitation of the prior art systems is that they employ a complex combination of stirrups and reinforcing bars that cannot be simply inserted into existing insulated concrete formwork or block masonry. Further, because of the complexity of the prior art systems, adjusting the angles, length and height of the cage formed by the stirrup or stirrups and the reinforcing bars, when those components are formed, is time consuming.

SUMMARY OF INVENTION

An object of the invention is to provide an improved structural system for use with existing block masonry or previously assembled insulated concrete formwork. A further object of the invention is to provide an improved structural system by placement of structural components partially or wholly in advance of assembly of insulated concrete formwork or laying of block masonry to form a structural component.

Accordingly, the invention herein comprises a system for reinforcing a building structural component having a plurality of webs. The system has a rigid continuous stirrup elongated along a longitudinal axis and configured into portions. The portions are insertable from a lateral direction into cells between the webs of the structural component in an unobstructed fashion. The stirrup is also configured so as to extend into at least one corridor along the length of the stirrup. The system also includes at least one longitudinal reinforcing member situated within the corridor.

A further embodiment of the invention comprises a building structural component in the form of a beam. The beam includes opposing rigid planar members with a plurality of webs spaced in parallel fashion between the planar members. The building structural component further includes a rigid continuous stirrup elongated along a longitudinal axis. The stirrup is positioned with the portions of the stirrup inserted into cells between the webs. The stirrup is also configured so as to extend into at least one corridor along its length. The building structural component also includes at least one longitudinal reinforcing member situated within the corridor.

The invention herein further comprises a method for reinforcing a building structural component having a plurality of webs in spaced planar configuration along the length of the component. The method includes the steps of placing a rigid continuous stirrup on a surface such that the stirrup extends into a lower corridor along its length and an upper corridor along its length. At least one longitudinal reinforcing member is then placed within the lower corridor. The building structural component is then superposed with the stirrup from a lateral direction such that portions of the stirrup are configured in cells between the webs and the stirrup extends into at least one corridor along its length. At least one longitudinal reinforcing member is then placed within the upper corridor. Finally, an adhesive substance is poured into the cells.

The invention also comprises a further method for reinforcing a building structural component having a plurality of webs in spaced planar configuration along the length of the component. The method includes the steps of superposing a rigid continuous stirrup with the building structural component from a lateral direction such that the stirrup extends into at least one corridor along the length of the stirrup and portions of the stirrup are inserted in cells between the webs. At least one longitudinal reinforcing member is then placed within each corridor. Finally, an adhesive substance is poured into the cells.

The invention also comprises a further method for reinforcing a building structural component having a plurality of webs in spaced planar configuration along the length of the component. The method includes the steps of suspending a rigid continuous stirrup on at least one longitudinal reinforcing member above a building structural component. The rigid continuous stirrup is then superposed with the building structural component from a lateral direction such that the stirrup extends into at least one corridor along the length of the stirrup, portions of the stirrup are inserted into cells between the webs and the at least one longitudinal reinforcing member is placed in an upper corridor along the length of the stirrup. A further at least one longitudinal reinforcing member is then placed within a lower corridor. Finally, adhesive is poured into the cells.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A system 10 for reinforcing a building structural component 14 is shown in FIG. 1. The building structural component 14 has a bottom surface 15 and a top surface 17 and opposing rigid planar members 20. The building structural component shown in FIG. 1 is insulated concrete formwork 18. The opposing rigid planar members 20 of the insulated concrete formwork 18 are insulation panels 24.

Webs 28 are also components of insulating concrete formwork 18. Where the building structural component 14 is insulated concrete formwork 18, the webs 28 are metal webs or plastic webs normally found in insulated concrete formwork 18. Such webs 28 have a lower cross portion 30 and an upper cross portion 31. The insulation panels 24 are orientated generally parallel to one another and the webs 28 are orientated generally normal to the insulation panels 24. The webs 28 are embedded in or otherwise attached to the insulation panels 24. The insulation panels 24 and webs 28 define a cell 32. Where there are more than two webs 28 in the insulated concrete formwork 18, there will be a multitude of cells 32. A continuous longitudinal space between the insulation panels 24 and below the lower cross portions 30 of the webs 28 and above the bottom surface 15 forms a lower corridor 34 and a continuous longitudinal space between the insulation panels 24 and above the upper cross portion 31 of the webs 28 and below the top surface 17 forms an upper corridor 36.

As seen in FIG. 8, the reinforcing system 10 may also be used with other building structural components 14 having a bottom surface 15 and a top surface 17. The building structural component 14 shown in FIG. 8 is block masonry 40. Such block masonry 40 includes opposing rigid planar members 20. The opposing rigid planar members 20 in block masonry 40 are face shells 44. Face shells 44 are orientated generally parallel to one another. A series of webs 28 joins the face shells 44. The block masonry 40 may be concrete masonry, wood fibre masonry, plastic masonry or any masonry that incorporates compartments. Where the building structural component 14 is block masonry 40, the webs 28 may be concrete, wood fibre, plastic or other suitable material found in masonry. The webs 28 are orientated generally perpendicular to the face shells 44. The face shells 44 and the webs 28 define a series of cells 32. Where there are more than two webs 28, there will be a plurality of cells 32. A continuous longitudinal space between the face shells 44 and below the webs 28 and above the bottom surface 15 forms a lower corridor 34 and a continuous longitudinal space between the face shells 44 and above the webs 28 and below the top surface 17 forms an upper corridor 36.

As seen in each of the figures, the structural reinforcing system 10 incorporates a continuous stirrup 60. The continuous stirrup 60 is elongated along a longitudinal axis. The continuous stirrup 60 is typically made from deformed steel rods or smooth steel rods. Preferably, continuous stirrup 60 is rigid. The continuous stirrup 60 may also be made from materials other than steel including carbon fibres, glass fibres or aramide fibres in the form of rods, rope, cloth or mesh. The continuous stirrup 60 can be supplied in lengths suitable for reinforcing all or part of the length of the structural component 14.

As shown in FIG. 2, the continuous stirrup 60 is configured to have a number of portions 70. The portions 70 include a plurality of legs 74 and may include one or more straight portions 78. There are two legs 74 between each of the straight portions 78 and the legs 74 are preferably straight. The continuous stirrup 60 may be formed such that two legs 74 occupy a cell 32. Alternatively, the continuous stirrup may be formed such that more than two legs 74 occupy a cell 32.

The angle x at which the legs 74 meet may also be varied at the time that the continuous stirrup 60 is being formed. The angle y at which the legs 74 meet the straight portions 78 may also be varied when the continuous stirrup 60 is being formed. The continuous stirrup 60 is formed such that the portions 70 of the continuous stirrup 60 are insertable from a lateral direction into the cells 32 of the building structural component 14 between the webs 28 in an unobstructed fashion. Alternatively, the continuous stirrup 60 is formed such that the structural component 14 is positionable over the previously positioned continuous stirrup 60 with the portions 70 of the continuous stirrup 60 fitting into the cells 32 of the structural component 14 in an unobstructed fashion.

As seen in FIG. 2, every second intersection of two legs 74 forms a lower loop 80. The lower loops 80 extend into a lower corridor 34 along the length of the continuous stirrup 60. The continuous stirrup 60 may be anchored at one or both ends of the continuous stirrup 60. In FIG. 2, an end 88 of the continuous stirrup 60 has an anchor 90.

The embodiment of the structural reinforcing system 10 shown in FIG. 2 also incorporates a single reinforcing member 100. The reinforcing member 100 may be an longitudinal reinforcing bar or the like. The reinforcing member 100 is linear and situated within the lower corridor 34. The reinforcing member 100 is generally parallel to the straight portions 78 of the continuous stirrup 60 and is situated proximate to the bottom surface 15 of the building structural component 14. The reinforcing member 100 is generally parallel to the insulation panels 24 of insulated concrete formwork 18 or the face shells 44 of block masonry 40. The straight portions 74 of the continuous stirrup 60 are distal from the bottom surface 15 of the building structural component 14.

A further embodiment of the structural reinforcing system 10 is shown in FIG. 3. This embodiment of the structural reinforcing system 10 incorporates two longitudinal reinforcing members. A first reinforcing member 110 is proximate to the bottom surface 15 of the structural component 14 and a second reinforcing member 114 is proximate to a top surface 17 of the structural component 14. The reinforcing members 110 and 114 are linear and generally parallel to one another. As shown in FIGS. 1 and 8, the first reinforcing member 110 is located in the lower corridor 34 and the second reinforcing member 114 is located in the upper corridor 36.

In the embodiment of the structural reinforcing system 10 shown in FIG. 3, the straight portions 74 of the continuous stirrup 60 have been replaced with a set of upper loops 120 proximate to the top surface 17 of the structural component 14. The upper loops 120 proximate to the top surface 17 of the structural component 14 extend into the upper corridor 36 which receives the second reinforcing member 114. One or more sets of two legs 74 of the continuous stirrup 60 may be inserted from a lateral direction into a cell 32 in an unobstructed fashion. Alternatively, the continuous stirrup 60 is formed such that the structural component 14 is positionable over the previously positioned continuous stirrup 60 with the legs 74 of the continuous stirrup 60 fitting into the cells 32 of the structural component 14 in an unobstructed fashion.

A further embodiment of the structural reinforcing system 10 is shown in FIGS. 5 and 5A. This embodiment of the structural reinforcing system 10 incorporates three longitudinal reinforcing members. Two reinforcing members 130 and 132 are proximate to the bottom surface 15 of the structural component 14. One reinforcing member 134 is proximate to a top surface 17 of the structural component 14. In a further embodiment of the structural reinforcing system 10 (not shown), two reinforcing members are proximate to the top surface 17 of the structural component 14 and a single reinforcing member is proximate to the bottom surface 15 of the structural component 14. In each embodiment of the reinforcing system 10 incorporating three reinforcing members 130, 132 and 134, the reinforcing members 130, 132 and 134 are linear and generally parallel to one another.

As seen in FIG. 5A, the continuous stirrup 60 is configured along its longitudinal axis in a triangular fashion. The reinforcing members 130 and 132 are situated in the lower corridor 34 and the reinforcing member 134 is situated in the upper corridor 36. The longitudinal reinforcing members 130, 132 and 134 are enclosed within the continuous stirrup 60.

A further embodiment of the structural reinforcing system 10 is shown in FIG. 6. This embodiment incorporates four longitudinal reinforcing members that are linear and are configured generally parallel to one another. Two of the reinforcing members 146 and 148 are located in the upper corridor 36 proximate to a top surface 17 of the building structural component 14 and two of the reinforcing members 150 and 152 are located in the lower corridor 34 proximate to a bottom surface 15 of the building structural component 14.

In the embodiment of the structural reinforcing system 10 shown in FIG. 6, vertical portions 160 of the continuous stirrup 60 extending between the reinforcing members 148 and 152 and the reinforcing members 146 and 150 are generally parallel to the planes of the webs 28. Top portions 162 of the continuous stirrup 60 extend between the reinforcing members 146 and 148 proximate to the top surface 17 of the structural component 14. The orientation of each of the top portions 162 may be parallel to the planes of the webs 28. Alternatively, the orientation of each of the top portions 162 may vary from parallel to the planes of the webs 28 so as to form an angle less than 90 degrees to the plane of the webs 28. Where the continuous stirrup 60 is inserted into existing insulated concrete formwork or block masonry, each of the top portions 162 may intersect the planes of the webs 28.

In the embodiment shown in FIG. 6, the continuous stirrup 60 also has bottom portions 164 extending between the reinforcing members 150 and 152 proximate to the bottom surface 15 of the structural component 14. Each of the bottom portions 164 may be oriented parallel to the planes of the webs 28 or at an angle less than 90 degrees to the planes of the webs 28. In the embodiment shown in FIG. 6, each of the bottom portions 164 extend so as to intersect the planes of the webs 28 where the continuous stirrup 60 is positioned prior to construction of the insulated concrete formwork or block masonry. Alternatively, the continuous stirrup 60 or portions of the continuous stirrup 60 may be compacted when formed such that only some bottom portions 164 intersect the plane of a web 28. The continuous stirrup 60 or portions of the continuous stirrup 60 may be extended when formed such that one or more bottom portions 164 intersect the planes of more than one web 28.

The continuous stirrup 60 of this embodiment of the structural reinforcing system 10 extends into both the lower corridor 34 and the upper corridor 36. The longitudinal reinforcing members 146 and 148 are situated within the upper corridor 36 and the longitudinal reinforcing members 150 and 152 are situated within the lower corridor 34. The longitudinal reinforcing members 146, 148, 150 and 152 are enclosed within the continuous stirrup 60.

A further embodiment of the structural reinforcing system 10 is shown in FIG. 7. This embodiment of the structural reinforcing system 10 incorporates four reinforcing members that are linear and configured generally parallel to one and other. Two reinforcing members 176 and 178 are located proximate to a top surface 17 of the structural component 14 and two reinforcing members 180 and 182 are located proximate to the bottom surface 15 of the structural component 14.

This embodiment of the structural reinforcing system 10 has vertical portions 186 of the continuous stirrup 60 extending between the reinforcing members 178 and 182 and the reinforcing members 176 and 180. One or more vertical portions 186 occupy a cell 32. Alternatively, the continuous stirrup 60 or portions of the continuous stirrup 60 may be compacted when formed such that only some vertical portions 186 intersect the plane of a web 28.

In this embodiment, the continuous stirrup 60 defines a rectangular-shaped reinforcing cage 188. The longitudinal reinforcing members 176 and 178 are located within upper corridor 36 and the longitudinal reinforcing members 180 and 182 are situated within the lower corridor 34. The vertical portions 186 and horizontal portions 190 and 192 of the continuous stirrup 60 may be formed at various angles to the plane of the webs 28 to minimize the amount of material required to form the continuous stirrup 60. The angles formed will accommodate the dimensions of the cells 32 and the requirements for intersecting the planes of the webs 28 depending on the construction sequence for inserting the continuous stirrup 60.

In operation, the continuous stirrup 60 is formed to enclose at least one longitudinal reinforcing member along its longitudinal axis. The dimensions of the building structural component 14 are taken into account when the continuous stirrup 60 is formed. The continuous stirrup 60 is formed such that portions of the continuous stirrup 60 may be inserted from a lateral direction into cells 32 between the webs 28. Alternatively, the continuous stirrup 60 is formed so that it may receive a building structural component 14 that is superposed with the continuous stirrup 60.

A further factor taken into account during the formation of the continuous stirrup 60 is the amount of reinforcement that is required. Where more reinforcement is needed, the continuous stirrup 60 will be configured such that there is a greater length of the continuous stirrup 60 in one or more cells 32. Alternatively, the continuous stirrup 60 may be formed such that portions of the continuous stirrup 60 do not extend through each cell 32, so as to limit the amount of material required to form the continuous stirrup 60.

The continuous stirrup 60 may also be formed to more efficiently control growth of any cracks that appear in the building structural component 14. FIG. 4 shows a building structural component 14 with a diagonal crack 200. The diagonal crack 200 starts at a point 202 proximate to an end of the building structural component 14 and ends at a point 204 proximate to the midspan of the structural component 14. A portion of the continuous stirrup 60 will intersect with the plane of the diagonal crack 200 at an angle z. It will be apparent to one skilled in the art that the angle z should approximate 90 degrees to maximize the reinforcement capacities of the structural reinforcing system.

Once the continuous stirrup 60 is formed, the continuous stirrup 60 may be placed on a surface. At least one longitudinal reinforcing member is then placed in the lower corridor 34. The building structural component 14 is then superposed with the continuous stirrup 60 from a lateral direction such that portions of the stirrup 60 are configured in cells 32 between the webs 28. At least one reinforcing member is then placed within the upper corridor 36. Finally, as seen in FIG. 1, an adhesive substance 210 is poured over the structural reinforcement system 10. The adhesive substance 210 is a substance that solidifies once it has dried, such as concrete, grout or the like. Preferably, the adhesive substance 210 fills the cells and all other spaces between the top surface 17 of the structural component 14 and the bottom surface 15 of the structural component 14. Once the adhesive substance 210 has dried, a beam is formed. It will be apparent to one skilled in the art that more than one course of insulated concrete formwork 18 or block masonry 40 may be used for reinforcement.

According to an alternative method, the continuous stirrup 60 is formed as described above. Thereafter, the continuous stirrup 60 is superposed with the structural component 14 from a lateral direction such that portions of the continuous stirrup 60 are inserted in cells 32 or chambers 52 between the webs 28. Thereafter, at least one reinforcing member is placed within each corridor. Finally, an adhesive substance 210 is poured over the structural reinforcing system 10. Preferably, the adhesive substance 210 fills the cells 32 or and any other spaces between the top surface 17 of the structural component 14 and the bottom surface 15 of the structural component 14. Once the adhesive substance 210 has dried, a beam is formed. It will be apparent to one skilled in the art that more than one course of insulated concrete formwork 18 or block masonry 40 may be used for reinforcement.

According to a further alternative method, the continuous stirrup 60 is formed as described above. Thereafter, the continuous stirrup 60 is suspended from at least one reinforcing member above the building structural component 14. The continuous stirrup 60 is then superposed with the building structural component 14 from a lateral direction such that the continuous stirrup 60 extends into at least one corridor along the length of the continuous stirrup 60. Portions of the continuous stirrup 60 will be inserted into cells 32 between the webs 28 of the building structural component 14. The at least one reinforcing member will be placed in an upper corridor 36 along the length of the stirrup 60. A further at least one reinforcing member is then placed within a lower corridor 34. Finally, an adhesive substance 210 is poured over the structural reinforcing system 10. Preferably, the adhesive substance 210 fills the cells 32 or and any other spaces between the top surface 17 of the structural component 14 and the bottom surface 15 of the structural component 14. Once the adhesive substance 210 has dried, a beam is formed. It will be apparent to one skilled in the art that more than one course of insulated concrete formwork 18 or block masonry 40 may be used for reinforcement.
